INTERGHANGEABLE RIFLE AND SHOTGUN BARREL.

Application filed May 13,

. stock of a rifle to permit interchangeability of rifle and gun shot barrels.

A further object of the invention is to provide a novel retaining means for either the rifle or gun shot barrel when placed in position upon the gun stock.

lVith the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a fragmentary side elevational view of a stock designed to permit interchangeability of rifle and gun shot barrels,

Figure 2 is a detail sectional view taken on line 2-2 of Fig. 1 showing the retaining screw for the barrel,

Figure 3 is a fragmentary side elevational view, partly in section showing another form of retaining means for the interchangeable barrel, and

Figure 4 is a detail sectional view taken on line 44 of Fig. 3.

The gun stock being of the usual construction and firing mechanism includes the stock 1 provided with the hinged trigger guard 2 that has a link connection 3 with the tilting barrel section 4 that is pivotally supported uponthe stock frame by the screw pin 5 as shown in Fig. 1. In guns of this character, a barrel is pivotally supported upon the stock frame by the screw pin 5, the barrel being movable upon its pivotal support to permit insertion of a cartridge in the breech end thereof. The barrel section 4 constitutes the inner end of the usual barrel, that is permanently carried by the stock frame with the outer end of the usual barrel severed therefrom to provide the stub barrel section. The barrel section 4 at its lower side carries a forward extension 6 that extends forwardly of the stock frame 1.

The barrel 7 which may be either a rifle or gun shot barrel carries the usual hand gripping block 8 and is provided with an end extension that is removably received in the barrel section 4, the inner end of the hand 1926. Serial N0. 108,918.

grippingblock 8 being bifurcated to receive the forward extension (3 of the stock frame 1. The lower face of the barrel 7 is provided with a recess 9 shown more clearly in Fig. 2 into which the end of the stud screw 10 received for retaining the barrel in position upon the gun stock, the screw 10 being threaded through the forward extension 6 of the stock frame. It ,will, therefore, be seen that upon releasing the screw 10 from the socket 9 the barrel 7 may be removed from the gun stock which permits interchanging of one type of barrel for another type. Also, when the tilting barrel section 4 is moved by its connection with the hinged trigger guard 2, the barrel 7 is moved therewith to position the inner end of the barrel for reception of a cartridge.

In the form of the invention shown in Figs. 3 and 4, a modified construction is illustrated for retaining the gun barrel in position on the stock, the end of the gun barrel 7 that is received in the barrel section 4 carrying a latch lever 11 pivoted to the under side thereof upon the pin 12 and carrying upon one end thereof forwardly of the pivot pin 12 a finger piece or plate 13 to be engaged by the retaining screw 10 carried by the extension 6, the plate 13 being normally moved away from the barrel 7 by the coil spring 14: interposedbetween said plate and barrel. The other end of the lever 11 is provided upon its end with a latch 15 that is received in the keeper socket 16 formed in the stock frame 17 in assembled formation as shown in Fig. 3. lVith the inner end of the barrel 7' within the barrel section 4 that is pivotally carried by the stock 1, the thread screw 10 is operated to engage the plate 13 against the tension of the spring 14 and move the latch lever 11 to position the latch lug 15 in the keeper socket 16 thereby locking the gun barrel upon the stock. To remove the gun barrel for interchangeable purposes, the stud screw 1.0 is released and the spring 14 automatically shifts the latch lever 11 to displace the latch lug 15 from the keeper socket, and at which time the barrel is readily detachable from the gun stock. It will, therefore, be seen that in each form of the invention, it is possible to provide a single gun stock with which either a rifle or a gunshot barrel is associated and thus embody" two types of fire arms in a single gun stock.

While there are herein shown and described the preferred embodiments of the present-invention, it is, nevertheless to be understood that minor changes may be made therein Without departing from the spirit and scope of the invention as claimed. '1

What is claimed is: A In a firearm of the type described, a gun stock, a pivotally mounted 7 barrelsection carried thereby, rifle and gun shot barrels interchangeably mounted in thebarrel section, an extension on the forward end of the barrel section, each of the barrels having a recess in its lower side anda stud screw carriediby the barrel section extension to enter the gun barrel recess to retain the gun bar'- rel in the barrel section, the barrel section,

andrifleor gunishot barrel mounted therein being movable as a unit on the pivotal support for the barrel section.

In testimony whereof I affix my signature.
